The 'center' in this stereo just combines left and right, it is completely useless. It isnt like a home stereo where the center is used for voices to make them more clear. I dont understand why they do that to so many car stereos now days.

Three weeks now after doing this and each day I like this stereo more. The bass level has really improved and channel seperation is much more noticeable. Basically the overall sound is much,much better. And it's reversable to stock in 5 minutes or less (but you won't go back!)

I am not an "Audiophile" by any strech, but this is an awesome change/upgrade and the price is right!

I must have spent a half hour to 45 minutes listening to various songs of different genres with and without that center speaker in place. I must be the only one here, but in the end.....I put it back in place hooked up.

Maybe listening through other sources makes a bigger difference or something, but for me, I listen to my music from a thumb drive and I definitely did not notice a huge difference.

What I did notice:
- Yes there may have been a bit of an improvement in seperation, but it wasn't huge. Maybe if I had listened to a track that more specifically makes use of left and right speakers purposely to fulfill an effect it would have stood out more.
- Bass does seem to come through more, and a bit louder at that, but its only because there is now less sound comming from the front of the cabin and you are able to hear the rears more clearly.
- Adding on to above point, I felt I had to turn up the volume a few clicks more to achieve the same desired volume level.
- Hope this makes sense, but at one point I closed my eyes and just tried to listen as closely as I could. With the center speaker in, it seemed like the sound source was higher, more level with my head. (To rephrase that in another way, imagine you have your eyes closed, and you hear a sound and you try to determine where it is comming from from the sound alone. ) Without the center in, it seemed as though the sound source was lower and not so "surrounding".
- Seemed like the treble....the really high tones were just not quite as loud.

To recap, if someone would have just suddenly taken my center speaker out without my knowing, I would have probably never even realized it, but trying it on your own you do notice subtle differences.

In my opinion (and going with my original thoughts) I think just adding one 10" subwoofer will make the system perfect. At that point I'll be able to turn down the bass and rely more on the large woofer, (which should stop any of that "buzzing" some of you might be hearing b/c there will be less of a strain on the speakers). By the way, my bass is only set on 5 or 6.

In the end, give it a shot...its easy to try, and maybe you will like it much more.

LOGIC 7 technology is a proprietary suite of surround algorithms developed and introduced by Lexicon.

LOGIC 7 technology is used for recording and distributing multi-channel sound on two channel media. It uses psychoacoustic techniques to restore the original channel separation with very little change in sound. LOGIC 7 technology offers a universal multi-channel sound solution.

It plays normal stereo recordings in full and satisfying surround, with a wide sound stage and increased envelopment, while standing ready to play encoded material in full surround. Multi-channel recordings encoded with LOGIC 7 technology, play in every system capable of handling two-channel material, and can be broadcast with standard equipment.

With the JBL MS-8 it takes it a step further actually utilizing your vehicle for what its meant to be and separating the channels to best suit the music's needs.
